no, you dont know what it is like to have those thoughts, I can understand how if must feel to see a loved one having taken his/her own life, and I feel for you.

but to have those thoughts, pushing you so close to the edge, that the only way you see as out, is down, its NOT bravery, its desperation!.

ive had those thoughts, and the only thing keeping me from it, was thinking about how the ones I cared about would feel, THAT stopped me, but sometimes that isnt enough, sadly, sometimes that person who feels that way needs help!
the signs can be hard to spot, and it will be too late in some cases.
